Kulkamp, who is said to have played guitar professionally for 20 years, also played a song entitled “Emanuel,” which he wrote for his newborn son, and other songs during the operation.

“I played six songs at certain times,” Kulkamp told local media of the surgery, per The Telegraph. “My right hand was a bit weaker because that was the side that they were operating on. So I stopped and rested. I was interspersing songs and talking with them.”

Kulkamp was reportedly kept conscious during the surgery so as to enable doctors to safely map the brain, allowing them to avoid injuring the organ in a way that would compromise important functions later on.

Since the brain has no pain receptors, keeping patients conscious during surgery is not entirely unusual.

It is unusual, however, for a patient to play music mid-operation -- though it has been done before.

In 2013, a California man named Brad Carter strummed on his guitar while surgeons worked to place a pacemaker in his brain. At the time, it was reported that Carter’s guitar-playing allowed doctors to find the best location for the device.

Four teenage girls born with no, or underdeveloped, vaginas have received new vaginal organs engineered from their own cells.

The patients had a condition called Mayer-Rokitansky-Küster-Hauser syndrome -- which means they had either no, or underdeveloped, vaginas. But researchers from Wake Forest Baptist Medical Center's Institute for Regenerative Medicine found a way to use these girls' own muscle and epithelial cells to create "scaffolds" in the shape of a vagina that were then implanted into each patient. Over time, the body absorbed the scaffolds and new tissue formed.
Now, up to eight years after the surgeries to implant <a href="http://www.huffingtonpost.com/2014/04/10/lab-grown-vaginal-organs-implanted-4-teens_n_5128702.html" target="_blank">these lab-engineered vaginas</a>, all of the patients have normal organ functioning, including no negative impacts on sexual functioning or desire.
